Major health concerns have been resolved in the twentieth century with the widespread implementation of water treatment technologies. By increasing the purity of water and by softening it, people have been able to eliminate numerous health issues, ranging from virus infections to heavy metal poisoning. The purpose of water treatment plants and their infrastructure is to remove organic and inorganic particles in water, prevent their appearance throughout the delivery process, and adhere to all chemical standards of quality.
In progressive countries, tap water is safe to drink; however, the process of water purification is lengthy and complicated. Water treatment facilities need to acknowledge numerous sources of contamination that they need to remove. In order for water to remain pure, an entire infrastructure must adhere to a strict set of standards set by the government. Despite previous concerns of health departments, the implementation of a thorough water treatment regulation was a reaction to a crisis. The origins of the initial spread of water treatment facilities in the United States lie in epidemics of typhoid and other waterborne diseases. The benefits of water treatment systems rapidly became apparent, and water safety and quality have become a primary concern since then.
